# Centos部署Docker环境 #

## 1.1 方式一：yum方式安装 ##

# 更新yum源
    yum update
    # 安装所需环境
    yum install -y yum-utils device-mapper-persistent-data lvm2
    # 配置yum仓库
    yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    # 安装Docker
    yum install docker-ce
    # 启动Docker
    systemctl start docker
    systemctl enable docker

## 1.2 方式二：（推荐安装方式） ##

curl -sSL https://get.daocloud.io/docker | sh

## 1.3 离线安装 ##

1.  下载docker的安装文件：https://download.docker.com/linux/static/stable/x86\_64/

![image-20210201092144600][]

1.  将下载后的tgz文件传至服务器，通过FTP工具上传即可
2.  解压`tar -zxvf docker-19.03.8-ce.tgz`
3.  将解压出来的docker文件复制到 /usr/bin/ 目录下：`cp docker/* /usr/bin/`
4.  进入\*\*/etc/systemd/system/**目录,并创建**docker.service\*\*文件

[root@localhost java]# cd /etc/systemd/system/
    [root@localhost system]# touch docker.service

1.  打开**docker.service**文件,将以下内容复制

[Unit]
    Description=Docker Application Container Engine
    Documentation=https://docs.docker.com
    After=network-online.target firewalld.service
    Wants=network-online.target
    
    [Service]
    Type=notify
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=192.168.200.128
    ExecReload=/bin/kill -s HUP $MAINPID
    # Having non-zero Limit*s causes performance problems due to accounting overhead
    # in the kernel. We recommend using cgroups to do container-local accounting.
    LimitNOFILE=infinity
    LimitNPROC=infinity
    LimitCORE=infinity
    # Uncomment TasksMax if your systemd version supports it.
    # Only systemd 226 and above support this version.
    #TasksMax=infinity
    TimeoutStartSec=0
    # set delegate yes so that systemd does not reset the cgroups of docker containers
    Delegate=yes
    # kill only the docker process, not all processes in the cgroup
    KillMode=process
    # restart the docker process if it exits prematurely
    Restart=on-failure
    StartLimitBurst=3
    StartLimitInterval=60s
    
    [Install]
    WantedBy=multi-user.target

1.  给docker.service文件添加执行权限：`chmod 777 /etc/systemd/system/docker.service`
2.  重新加载配置文件：`systemctl daemon-reload`
3.  启动Docker `systemctl start docker`
4.  设置开机启动：`systemctl enable docker.service`
5.  查看Docker状态：`systemctl status docker`

如出现如图界面，则表示安装成功！
